Abstract
The utility model discloses a cambered surface is from crowded bolt, including nut and screw rod, characterized by: the screw rod is equipped with the external screw thread, the external screw thread cross -section is the class triangle -shaped on arc limit. This bolt is from crowded efficient, and this bolt is high with locking intensity with the threaded connection intensity of extruding certainly.
Description
Technical field
The utility model relates to a kind of cambered surface from squeezing bolt.
Background technique
When large foundry goods, ironcasting needs be bolted miscellaneous part, because foundry goods directly can not cast out screw thread, screw thread is made again after generally all getting out base hole in advance, operation is various, time and human cost are comparatively large, and plain bolt is in use easy occurs to loosen because of outside cause, and locking intensity is low.
Model utility content
In view of the deficiency that background technique exists, technical problem to be solved in the utility model is to provide that a kind of structure is simple, join strength and the high cambered surface of locking intensity be from squeezing bolt.
The utility model takes following technological scheme: cambered surface is from squeezing bolt, and comprise nut and screw rod, described screw rod is provided with outside thread, and described outside thread cross section is the class triangle of arc-shaped side.
Described class three sides of a triangle are camber line, and the center of described class triangle point-to-point transmission straight line is 0.6 decimillimeter to the distance of camber line.
In the utility model, this cambered surface is simple from squeezing bolt arrangement, and without the need to making internal thread in advance in base hole, externally threaded cross section is the class triangle of arc-shaped side, high from the efficiency of the internal thread squeezed in base hole in use, and the outside thread of this bolt and the power producing a kind of mutual locking from the internal thread squeezed each other, greatly improve intensity and the locking intensity of connection.
Accompanying drawing explanation
The utility model has following accompanying drawing:
The structural plan schematic diagram of the certainly crowded bolt of cambered surface that Fig. 1 provides for model utility.
Fig. 2 is the A-A cross-sectional schematic of the cambered surface in Fig. 1 from crowded bolt.
Embodiment
Drawings illustrate the technical solution of the utility model and embodiment, further describe each details and the working principle thereof of embodiment below more by reference to the accompanying drawings.
With reference to shown in Fig. 1, Fig. 2, a kind of cambered surface that the utility model provides is from squeezing bolt, comprise nut 1 and screw rod 2, described screw rod 2 is provided with outside thread 3, described outside thread cross section is the class triangle of arc-shaped side, three limits of described class triangle 4 are camber line 5, and the center of described triangle 4 point-to-point transmission straight line 6 is 0.6 decimillimeter to the distance of camber line 5.
Use this cambered surface from squeezing bolt, ironcasting only need getting out base hole, eliminate the operation of screw thread processed, directly carrying out from squeezing tapping with electrical equipment, outside thread 3 and the power producing a kind of mutual locking from the internal thread squeezed each other of this bolt, improve intensity and the locking intensity of connection greatly.
